The National Center for Health Statistics estimates that 16.9 percent of U.S. children and adolescents aged 2 to 19 were obese in 2009-2010. Assume that this obesity rate holds true today. If you were to randomly select 15 U.S. children or adolescents, find each of the following: Note1: carry at least 6 digit precision for any intermediate calculations then round your answer to 4 decimal places Note2: Any value that is less than 0.0001, (1 x 10-4) , can be rounded to 0 A) The probability that at most 2 people are obese is:  B) The probability that exactly 3 people are obese is:  C) The probability that none of the people are obese is:  D) The probability that at least 2 people in the sample will be obese is

A polling company reported that 53% of 2302 surveyed adults said that they play football. Complete parts (a) through (d) below. a. What is the exact value that is 53% of 2302? The exact value is (Type an integer or a decimal.) b. Could the result from part (a) be the actual number of adults who said that they play football? Why or why not? OA. Yes, the result from part (a) could be the actual number of adults who said that they play football because the polling numbers are accurate. OB. No, the result from part (a) could not be the actual number of adults who said that they play football because that is a very rare activity. OC. Yes, the result from part (a) could be the actual number of adults who said that they play football because the results are statistically. significant. O D. No, the result from part (a) could not be the actual number of adults who said that they play football because a count of people must result in a whole number. c. What could be the actual number of adults…

It was reported in 2007 that there were 8,758,000 people age 16 or older who had a "go outside the home" disability and that this was 22.2% of the population (of this age group). These are people who cannot go outside the home without help. How large was the total population (of this age group) in 2007? The population in 2007 of people (of this age group) is (Round to the nearest thousand people as needed.) people.

A 2014 Pew Research Center Survey asked 2,002 adults about the intersection of politics and science. Of the survey participants, 1,281 responded "neither" when asked if they perceive scientists as politically liberal or conservative. What are the values of p′, "successes", or the estimated proportion of Americans who perceive scientists as neither politically liberal or conservative, and q′, the estimated proportion of Americans who perceive scientists as politically liberal or conservative? Answer in decimal form, rounding to the nearest hundredth.
